Camera module and reflecting module

Abstract

A camera module includes: a housing having an internal space; a reflecting module including a reflecting member and including a moving holder movably supported by an inner wall of the housing disposed in the internal space; and a lens module disposed behind the reflecting module disposed in the internal space and including a lens barrel including lenses aligned in an optical axis direction so that light reflected from the reflecting member is incident thereto, wherein the moving holder is provided to be movable in one axis direction approximately perpendicular to the optical axis direction with respect to the housing, and the lens module is provided with a carrier to which the lens barrel is supported, configured to be movable in the other axis direction approximately perpendicular to the optical axis direction and the one axis direction with respect to the housing.

What is claimed is: 
     
       1. A camera module comprising:
 a housing having an internal space; 
 a reflecting module disposed in the internal space, and comprising a reflecting member and a moving holder movably supported by an inner wall of the housing; and 
 a lens module disposed behind the reflecting module in the internal space, comprising a lens barrel comprising lenses aligned in an optical axis direction configured such that light reflected from the reflecting member is incident to the lenses, 
 wherein the moving holder is configured to be movable in one axis direction approximately perpendicular to the optical axis direction with respect to the housing, and 
 wherein the lens module comprises a carrier supporting the lens barrel, 
 wherein the lens barrel is configured to be movable in another axis direction approximately perpendicular to the optical axis direction and the one axis direction with respect to the carrier, and 
 wherein the carrier is configured to be movable in the optical axis direction relative to the housing. 
 
     
     
       2. The camera module of  claim 1 , wherein the moving holder is configured to be rotatable around the other axis with respect to the housing. 
     
     
       3. The camera module of  claim 2 , further comprising two or more ball bearings disposed between the moving holder and the housing, wherein the two or more ball bearings are aligned on the other axis. 
     
     
       4. The camera module of  claim 3 , wherein the ball bearings are disposed in the moving holder or the housing to be freely movable. 
     
     
       5. The camera module of  claim 4 , wherein the ball bearings have a spherical or a cylindrical shape. 
     
     
       6. The camera module of  claim 3 , wherein the ball bearings are fixedly disposed in the moving holder or the housing. 
     
     
       7. The camera module of  claim 6 , wherein the ball bearings have a spherical shape, a hemispherical shape, a cylindrical shape, a semi-cylindrical shape, or a rounded protrusion shape. 
     
     
       8. The camera module of  claim 1 , wherein the moving holder is configured to move linearly along one axis with respect to the housing. 
     
     
       9. The camera module of  claim 1 , further comprising two or more ball bearing sets disposed between the moving holder and the housing, wherein the two or more ball bearing sets are disposed aligned in the one axis direction. 
     
     
       10. The camera module of  claim 9 , wherein the ball bearing sets are fixedly disposed in the moving holder or the housing or are provided in the moving holder or the housing to be freely movable. 
     
     
       11. The camera module of  claim 1 , wherein the housing and the moving holder comprise a pulling magnet or a pulling yoke, respectively, and the moving holder is supported by the inner wall of the housing by attractive force between the pulling magnet and the pulling yoke. 
     
     
       12. The camera module of  claim 1 , wherein two or more ball bearing sets aligned in the other axis direction are disposed between the lens barrel and the carrier. 
     
     
       13. The camera module of  claim 1 , wherein the lens barrel comprises a pulling yoke allowing the lens barrel to be supported by the carrier by attractive force between the pulling yoke and a driving magnet of the carrier. 
     
     
       14. The camera module of  claim 1 , wherein the carrier comprises a stopper preventing separation of the lens barrel. 
     
     
       15. The camera module of  claim 1 , wherein the carrier is configured to be movable in the optical axis direction with respect to the housing. 
     
     
       16. The camera module of  claim 1 , further comprising a main board disposed on side surfaces and a bottom surface of the housing, wherein the main board comprises coils for driving the lens module and the reflecting module mounted thereon. 
     
     
       17. The camera module of  claim 16 , wherein the main board is a double-sided substrate,
 the coils are mounted on an inner surface of the main board toward the internal space of the housing, and 
 a gyro sensor is mounted on an outer surface of the main board opposing the inner surface of the main board. 
 
     
     
       18. A portable electronic device comprising the camera module of  claim 1 . 
     
     
       19. A portable electronic device of  claim 18 , wherein the optical axis direction is generally perpendicular to a thickness direction of the portable electronic device.
